July 2013 General Discussion

[michsnowfreak]

Well after being drenched with storm after storm, my backyard sat on the sidelines the last two days (0.03" yesterday, T today). Now sunshine, low humidity, and AMAZING July weather is about to commence the next several days. The wait continues for Detroit's first 90F of the year. With no 90F almost a guarentee through at least the 13th...2013 is certainly moving up the ranks for latest first 90F day on record (since 1887). Even more impressive is that most of those are a LONG time ago...in fact only 3 times (1951, 1960, 1979) in the last 95 years have we gone as late into the summer as we will be in 2013.

1907 – no occurrence - (0 days)

1915 – no occurrence - (0 days)

1912 – August 31 ----- (4 days) 

1979 – August 2 ------ (1 day)

1917 – July 29 ------- (5 days)

1960 – July 22 ------- (5 days)

1918 – July 20 ------- (15 days)

1904 – July 17 ------- (3 days)

1905 – July 17 ------- (3 days)

1951 – July 16 ------- (7 days)

2013 - ???

 

With several clear days expected...we finally breaking out of a crazy cloudy start to July. i have never seen anything like it. Check out the F6 for Detroit.....the skycover EVERY DAY July 1-9 has been 9, which means a near solid overcast with just a few scattered breaks. They don't do the old "% of possible sunshine" stat anymore, but July is our sunniest month on average (69% of possible sunshine being the average). I would estimate we have had at MOST 10% of possible sunshine the first 9 days of the month, probably less. Thats crazy considering its nearly a third of the way through what should be our sunniest month. By comparison...our cloudiest month, December, averages 30% of possible sunshine.

1918 is interesting, the first 90 is really late.... Then the season racks up an above normal amount for the season afterward.

[Chicago WX]

Dewpoints in the mid 50's this morning...ah, much nicer.

 

Just one day of 90º+ temps at LAF so far this year. At this point last year, we were at 26 days...five of them being 100º+. Again, much nicer this year.

[Chicago WX]

time sensitive but 96 frame loop for LOT on the COD site is pretty cool right now.

 

Saw this last evening...and it was very cool.

[T-Storm]

Hey all.  New here from the Milwaukee area.  Looking forward to contributing.  Excited to finally see a warm and dry period coming up.  It's been a bummer for outdoor activities this year. 

[Brewers]

What a refreshing morning. RAC had a low of 58 and BUU made it down to 52.

Anybody buying into this retrograding upper level Low --From IND AFD

 

LONG TERM /SUNDAY THROUGH THURSDAY/  
 
ISSUED AT 259 AM EDT THU JUL 11 2013  
 
THE MAIN FOCUS OF THE LONG TERM PERIOD CONTINUES TO BE AN UPPER  
LEVEL LOW THAT ORIGINATES OVER THE NORTHEAST U.S. AND RETROGRADES  
BACK INTO THE OHIO VALLEY AND CENTRAL U.S. LATEST INITIALIZATION  
HAS COMPLETELY SWITCHED FROM A DRY FORECAST IN THE EXTENDED AS  
ORIGINALLY FORECASTED THE LAST FEW NIGHTS...TO NOW BRINGING PRECIP  
INTO CENTRAL INDIANA FOR THE MAJORITY OF EXTENDED PERIOD IN  
ASSOCIATION WITH THAT UPPER LOW. FOR NOW...DECIDED TO GO WITH  
SLIGHT CHANCE POPS OVER MOST OF THE PERIOD SINCE MODELS DO TAKE  
THAT LOW MORE DIRECTLY OVER CENTRAL INDIANA NOW AS OPPOSED TO THE  
TENNESSEE VALLEY INDICATED IN EARLIER RUNS. HOWEVER...WOULD NOT  
PUT HIGH CONFIDENCE IN THIS FORECAST DUE TO THE DRASTIC SWITCH IN  
MODELS FROM RUN TO RUN. A WARM MOIST ENVIRONMENT WILL BE IN PLACE  
DAILY TO CONTRIBUTE TO DESTABILIZATION AND DIURNAL THUNDERSTORMS.  
HIGH TEMPS WILL BE IN THE UPPER 80S WITH DEWPOINTS IN THE UPPER  
60S/LOW 70S.

Beautiful day for about Mid-July. 77°/54° at 2pm here. Got down to a comfortable 58° this morning. 

[Chinook]

More rain today. Golf game is gonna start goin to hell soon

Based on CoCoRAHS precipitation reports, Perrysburg has gotten 1.1" in Late May, 9.44" in June and 5.15" in July. Perrysburg Ohio probably hasn't had over 9.0" in any month in any time that I can remember.

[Hoosier]

Dewpoints much more comfortable today. Looks like temp will come up short of 80. Let's see how low we go tonight.

[Geos]

Peaked at 77° today. Perfect day for just about any outdoor activity! 

[Chitown Storm]

79/53 here right now. Humidity down to 38%. One of the best evenings of the summer.

[Brewers]

Even better radiational cooling setup than last night. High pressure directly overhead and dewpoints around 50. Lower 50's a possibility?

[Geos]

66°/49° here right now. Feels great! I'm betting areas away from the lake have a shot at lower 50s.

[Chitown Storm]

Probably a good shot at lower 50's here in the Fox Valley...typical cool spot.

66°/49° here right now. Feels great! I'm betting areas away from the lake have a shot at lower 50s.

[Chicago WX]

79. Glorious.

And 52 is my call for the low...LAF effect.

[Brewers]

66°/49° here right now. Feels great! I'm betting areas away from the lake have a shot at lower 50s.

 

 

Yeah typical cold spots like BUU and SBM have a good chance. Winds have decoupled pretty much everywhere already, down to 62 here.

[Hoosier]

79. Glorious.

And 52 is my call for the low...LAF effect.

Sounds about right. If we can get the winds to go calm for any length of time then sub 50 may be a possibility, though I'd only give it like a 20% chance.

[Geos]

60°/55° right now. Mid 50s here a good bet at least. UGN seems to radiate out well if there is no marine influence.

[LizardMafia]

79. Glorious.

And 52 is my call for the low...LAF effect.

You came pretty damn close with 53!

[hm8]

Upper 80s/Lower 90s in DTW's forecast now Sunday through Thursday

[weatherbo]

46 this morning, second time this July I've had 46 for a low. Grayling hit 41 this morning.

[Brewers]

Pretty cool morning for mid-July. 53 here at RAC, 56 at MKE, 49 at ENW and 47 at BUU.

[Chicago WX]

You came pretty damn close with 53!

 

Yep, damn. Two consecutive hourly readings of 53º...thought we could intra hour a 52º, but no dice.

[Chicago WX]

First 1/3-ish of July in the books. Average temperature departures in Indiana, through the 11th:

 

Indianapolis Eagle Creek: -3.8º

Lafayette: -3.4º

Muncie: -2.9º

Terre Haute: -2.7º

Evansville: -2.6º

Indianapolis: -2.6º

IWX: -2.2º

South Bend: -2.0º

Bloomington: -1.6º

Fort Wayne: -1.5º

Goshen: -0.5º

 

Seasonably warm/hot starting next week, so these will be knocked back.

[wisconsinwx]

Surprisingly it got down into the 40s in some locations in SE Wisconsin this morning.

[SpartyOn]

The DTW streak of sub 90 readings might be toast next week.

[hm8]

The DTW streak of sub 90 readings might be toast next week.

NAM thinks so

 

Sunday:

 

 

Monday:

 

[daddylonglegs]

Sure looks like the "dog days" of summer about to set in...AC is ready and willing.  Yesterday we touched 87F and dropped to 63F this morning...    Took the oldest kid to the beach yesterday...Mississippi still like chocolate milk.    There is actually a "mud line" where the Black and Mississippi Rivers meet..with the Black River being a lot clearer. 

[michsnowfreak]

1918 is interesting, the first 90 is really late.... Then the season racks up an above normal amount for the season afterward.

Yup....92F on July 20th was the first of the year, but from July 20-28th, 7 of the 9 days were 90F+. August 5-8th featured a deadly heatwave including Augusts hottest temp on record (104F on 8-6-1918) as well as the highest mean temp (91F) for Detroit on record! (Departure of +19F on August 6th). A 2-day repreive was followed by another 3-day heatwave Aug 11-13th. A few more scattered 90s and boom..you have a summer void of heat til late July that more than made up for lost time.
